mandibulectomy

Resection of part of the mandible for cancer of the oral cavity, especially of the floor of the mouth; mandibulectomies can be either marginal (in which only the bone, teeth and adjacent soft tissues are resected and the mandible’s continuity is maintained) or segmental (where a complete segment of the mandible is removed).

His method started with a midline bisection of the lower lip, then by segmental mandibulectomy and in-continuity radical neck dissection.

Surgical management of ameloblastoma in the mandible: segmental mandibulectomy and immediate reconstruction with free fibula or deep circumflex iliac artery flap (evaluation of the long-term esthetic and functional results).
Numerous factors might contribute to the exposure of reconstruction plates used for primary mandibular reconstruction after mandibulectomy.

Approximately one month after the last treatment, radiographs, CT, lymph node biopsy, and a physical exam were performed to determine the status of the tumor and evaluate the feasibility of a mandibulectomy to remove the SCC.
